class langchain_community.document_loaders.parsers.pdf.PDFMinerParser(extract_images: bool = False, *, concatenate_pages: bool = True)[source]¶

Parse PDF using PDFMiner.

Initialize a parser based on PDFMiner.

Parameters

  • extract_images (bool) – Whether to extract images from PDF.

  • concatenate_pages (bool) – If True, concatenate all PDF pages into one a single document. Otherwise, return one document per page.

Methods

__init__([extract_images, concatenate_pages])

__init__(extract_images: bool = False, *, concatenate_pages: bool = True)[source]¶

Initialize a parser based on PDFMiner.

Parameters

  • extract_images (bool) – Whether to extract images from PDF.

  • concatenate_pages (bool) – If True, concatenate all PDF pages into one a single document. Otherwise, return one document per page.

lazy_parse(blob: Blob) → Iterator[Document][source]¶

Lazily parse the blob.

Parameters

blob (Blob) –

Return type

Iterator[Document]

parse(blob: Blob) → List[Document]¶
